The 1996 Dodge Stealth (rebadged Mitsubishi 3000GT) is a complex sports car with AWD and twin-turbo variants that suffer from heat-related engine failures, transmission cooler leaks, and expensive drivetrain repairs. The platform's tight engine bay and labor-intensive design make even routine repairs costly.
Crankshaft Walk / Thrust Bearing Failure (Twin Turbo)
Common · high severityTypical onset: 60,000-100,000 mi
Symptoms: Metallic grinding or knocking from engine bay, especially during throttle transitions, Check engine light with crank position sensor codes, Severe cases: catastrophic engine failure with oil loss and metal shavings in oil
Fix: Requires engine removal and complete disassembly to replace thrust bearings and machine crankshaft if scored. Expect 25-35 hours labor due to tight bay and AWD/turbo complexity. Many shops recommend full engine rebuild at this point since you're already in there.
Estimated cost: $4,500-8,000
Transmission Oil Cooler Line Failure
Common · high severityTypical onset: 70,000-120,000 mi
Symptoms: Transmission fluid leaking from front of vehicle near radiator, Pink or red fluid mixing with coolant in overflow tank, Transmission slipping or delayed engagement after leak begins, Overheating transmission in hot weather or under load
Fix: Steel cooler lines corrode and rupture where they connect to radiator or run along frame rails. Replacement requires dropping front crossmember on AWD models. If fluid mixed into coolant, transmission flush is mandatory. 6-10 hours labor depending on AWD/FWD.
Estimated cost: $800-1,500
Head Gasket Failure (Both Banks)
Occasional · high severityTypical onset: 80,000-140,000 mi
Symptoms: White smoke from exhaust on cold start, Coolant loss with no visible external leaks, Milky oil on dipstick or under oil cap, Rough idle and misfires on affected cylinder bank
Fix: The transverse V6 layout makes this a nightmare job requiring intake manifold, turbos (if equipped), timing belt, and extensive accessory removal. Both banks typically done together. 18-28 hours labor. Must resurface heads and replace timing components while apart.
Estimated cost: $3,500-6,000
Transfer Case Viscous Coupling Failure (AWD)
Occasional · medium severityTypical onset: 90,000-150,000 mi
Symptoms: Binding or hopping when making tight turns at low speed, Clunking from center of vehicle during acceleration, Drivetrain vibration at highway speeds, In severe cases: complete loss of rear-wheel drive power
Fix: The viscous coupling unit in the transfer case wears out and can seize. Transfer case removal requires exhaust, driveshaft work, and transaxle separation. Used units are getting scarce. 12-16 hours labor. Note: this was subject to NHTSA recall but many were never addressed.
Estimated cost: $2,200-3,800
Turbocharger Failure and Oil Line Issues (Twin Turbo)
Occasional · medium severityTypical onset: 80,000-120,000 mi
Symptoms: Blue smoke on acceleration or deceleration, Whistling or grinding noise from engine bay under boost, Loss of boost pressure and sluggish acceleration, Oil consumption increases noticeably (1 qt per 500-1000 miles)
Fix: Turbos fail from age, heat cycling, and oil starvation from clogged feed lines. Access requires removing intake plenum and intercooler piping. Factory oil feed lines crack. Smart shops replace both turbos and all oil lines together. 14-18 hours for both turbos plus lines.
Estimated cost: $2,800-4,500
Engine and Transmission Mounts Deterioration
Common · low severityTypical onset: 60,000-100,000 mi
Symptoms: Excessive engine movement visible when revving in park, Clunking when shifting from reverse to drive, Vibration through chassis at idle, Transmission shifter feels loose or vague
Fix: Hydraulic mounts wear out and cause driveline slop. Front mount accessible but rear requires significant disassembly. Transmission mount needs subframe support. All three typically done together. 5-8 hours labor.
Estimated cost: $900-1,400
Only buy if you're handy with tools and have $3-5k set aside for immediate engine/trans work—these are spectacular cars when sorted, but most examples are ticking time bombs from deferred maintenance and known platform weaknesses.
